OverviewA group of travelers stumbles upon an ancient burial ground in a marsh in Cape Cod and unleashes an unspeakable horror. Bruised, bloody and having already lost two friends to their ordeal, they stumble out of the marsh and find an empty house, where they gratefully take refuge. Much to their horror, however, they discover that there is an even deeper malice at work in this house. Their fight to survive grows even more intense as they debate whether the horror inside the house or the horror in the marsh is worse and whether it's possible to escape either one.
